Random Generator (java)

(Generating random characters) Use the methods in RandomCharacter to print one hundred uppercase letters and then one hundred single digits, and print ten per line.
Use these methods:
public static char getRandomUppercaseLetter(){
return getRandomCharacter('A', 'Z');
}
public static char getRandomDigitCharacter(){
return getRandomCharacter('0', '9');
}

I just don't know how to work it into these methods. Try and keep it simple, i'm still new to coding.
Thanks!

(that is the question)
But the methods listed in 5.10 (a different page) were this:

Its a question in my text book. I have to create a code that outputs 100 random Capital Letters and 100 random numbers... and they have to be 10 to a line. And I have to use one or more of the methods I listed above. Its a homework assignment that i've given up on.

Hi. so this is actually a continuation from another question of mine[Here](https://www.daniweb.com/programming/software-development/threads/506795/dynamically-add-values-into-datagridview-cell-from-listbox-vb2010) but i was advised to start a new thread as the original question …

I have a 2d matrix with dimension (3, n) called A, I want to calculate the normalization and cross product of two arrays (b,z) (see the code please) for each column (for the first column, then the second one and so on).

Write a C program that should create a 10 element array of random integers (0 to 9). The program should total all of the numbers in the odd positions of the array and compare them with the total of the numbers in the even positions of the array and indicate ...
